Verifying and validating software requirements and design specifications Adopteddating site
Note: Verification begins before Validation and then they run in parallel until the software product is released.
It would imply to verify if the specifications are met by running the software but this is not possible (e. Only by reviewing its associated artifacts, someone can conclude if the specifications are met.
It is entirely possible that a product passes when verified but fails when validated.
This can happen when, say, a product is built as per the specifications but the specifications themselves fail to address the user’s needs.
g., how can anyone know if the architecture/design/etc. The output of each software development process stage can also be subject to verification when checked against its input specification (see the definition by CMMI below).
Examples of artifact verification: Software validation checks that the software product satisfies or fits the intended use (high-level checking), i.e., the software meets the user requirements, not as specification artifacts or as needs of those who will operate the software only; but, as the needs of all the stakeholders (such as users, operators, administrators, managers, investors, etc.).
If such artifact is incomplete or wrong, the developers will not be able to build the product the stakeholders want.
This is a form of "artifact or specification validation".
Building the right product implies creating a Requirements Specification that contains the needs and goals of the stakeholders of the software product.To ensure that the product actually meets the user’s needs and that the specifications were correct in the first place.In other words, to demonstrate that the product fulfills its intended use when placed in its intended environment.Every time the output of a process correctly implements its input specification, the software product is one step closer to final verification.If the output of a process is incorrect, the developers are not building the product the stakeholders want correctly.
